What does the Bible say about faith and doubt?

In John 11, we see the interplay of faith and doubt through the character of Thomas, often labeled as 'Doubting Thomas.' However, Thomas demonstrates a desire to be part of Christ's mission, stating, 'Let us go, that we may die with him.' This reflects a profound, albeit troubled, faith. The Scripture encourages believers that faith is ultimately a gift from God, not dependent on human merit. Hebrews 11:1 defines faith as 'the assurance of things hoped for, the conviction of things not seen.' Therefore, in the midst of our doubts, we are called to look to Christ, who is the author and perfecter of our faith.
